An NSF Mid-scale Research Infrastructure project

Differential Pressure Gauge

Short-period seafloor pressure variations capturing tsunami signals and hydroacoustic waves.

Overview

A differential pressure gauge on the cabled ocean-bottom seismometer measures short-period seafloor pressure variations, capturing tsunami signals and hydroacoustic waves. Data are streamed at several sample rates.

Stations

The table below lists the station, location code, and channels for the data.
